Result

One UPI search checks a plot against 11 national map layers, and says “Unknown” when a source has no data.

  • Unknown

    shown when a source has no data, never a guess

  • 11

    national map layers checked in one UPI search

  • 4 pages

Architecture

01 / Context

Buyers, lenders and developers in Rwanda have to piece together a plot’s boundaries, zoning, risks and value from separate sources before they can trust a deal. In May 2026 I started building Trustplot to put that picture in one place.

02 / What I built

A full-stack land and property intelligence platform: parcel search by UPI, interactive satellite mapping, zoning and risk screening, reference valuation, and automated report generation. Spatial property data lives in PostGIS.

03 / Hard parts

Integrating ArcGIS REST services and geospatial datasets into parcel-level answers, and being explicit when a source has no data: the workspace shows “Unavailable” or “Unknown” rather than guessing.

04 / Outcome

A working platform where one UPI search returns the parcel boundary, area, location (district, sector, cell), reference land value and screening results, ready to export as a report.
